Tyrosine-protein phosphatase non-receptor type 6, also known as Src homology region 2 domain-containing phosphatase-1 (SHP-1), is an enzyme that in humans is encoded by the PTPN6 gene. [5] The protein encoded by this gene is a member of …

Apr 15, 2016 · Src homology 2 domain-containing protein tyrosine phosphatase 1 (SHP-1) is a widely expressed inhibitory protein tyrosine phosphatase (PTP). In T-cells, it is a negative regulator of antigen-dependent activation and proliferation.

SHP-1 [protein tyrosine phosphatase, non-receptor type 6 (PTPN6)] is expressed by all mature haematopoietic lineages and at low levels, in a different isoform, by endothelial cells . There is 95% homology between human and mouse SHP-1, …

SHP-1 or PTPN6 (previously also referred to as SH-PTP1, PTP1C, HCP, or Hcph) is expressed predominantly in hematopoietic cells of all lineages and all stages of maturation, while it is expressed at low levels in epithelial cells (21, 26–28, 31).

Feb 6, 2024 · Here we demonstrate that inhibition of tyrosine phosphatase SHP-1 in LSCs increases their glycolysis and oxidative phosphorylation, enhancing their sensitivity to chemotherapy and vulnerability...

Shp1 is a cytosolic tyrosine phosphatase that regulates a broad range of cellular functions and targets, modulating the flow of information from the cell membrane to the nucleus.

Apr 21, 2024 · Detailed studies have shown that SHP-1 regulates SHP2 expression, and SHP-1 and SHP2 are involved in macrophage M2 polarisation. SHP-1 inhibits HOXA10 and TGFβ2 which in turn regulates the...

SHP-1, 2 promote cell growth and act by both upregulating positive signaling pathways and by downregulating negative signaling pathways. SHIP is another inhibitory phosphatase that is specific for the inositol phospholipid phosphatidylinositol-3,4,5-trisphosphate (PIP3).

Mar 13, 2003 · SHP-1, an SH2 domain-containing protein tyrosine phosphatase, is primarily expressed in hematopoietic cells and behaves as a key regulator controlling intracellular phosphotyrosine levels in lymphocytes.

This review focuses on the roles of the two cytoplasmic PTPs, the Src-homology 2 domain (SH2)-containing SHP-1 and SHP-2, in T-cell signaling, development, differentiation, and function. Tyrosine phosphorylation and dephosphorylation of proteins play a …
